There are instances when you will want to provide additional information, such as the name or description of the DataGridView control, to accessibility client applications. There are two ways of providing this additional information. To provide limited accessibility information for existing controls, set the control's AccessibleName and AccessibleDescription property values, which will be reported to accessibility client applications.

The DataGridView exposes its data structure by using AccessibleRole values to define the data table hierarchy. For more information on exposing data tables to Microsoft Active Accessibility, see "Exposing Data Tables through Microsoft Active Accessibility" in the MSDN library at http://msdn.microsoft.com/library.
